3.25 BIO FUEL IN DEUTZ ENGINES
General
Use of bio fuels is permitted for the compact engines made by
DEUTZ.
Distillate fuels with residue oil percentages or mixed fuels may
not be used in DEUTZ compact engines.
The DEUTZ vehicle engines are designed for diesel fuels in
accordance with EN 590 with a cetane number of at least 51.
DEUTZ engines for mobile machinery are designed for a cetane
number of at least 45. When using fuels of a low cetane num-
ber, disturbing white smoke and ignition misfires are to be
expected under some circumstances.
A cetane number of at least 40 is permissible for the US market,
therefore special engine models have been developed to
avoid starting difficulties, extreme white smoke or increased
hydrocarbon emissions (EPA specification - US EPA REGULA-
TIONS FOR LARGE NONROAD COMPRESSION-IGNITION
ENGINES).
If the white smoke behavior is unacceptable when using a very
low cetane number, the use of ignition improvers is to be rec-
ommended as a later remedial measure.
The certification measurements for compliance with the legal
emission limits are carried out with the test fuels prescribed by
law. These correspond to the diesel fuels in accordance with
EN 590 and ASTM D 975. No emission values are guaranteed
with the other fuels described. It is the obligation of the owner
to check the permission for use of the fuels in accordance with
regional regulations.
Bio Fuel
PERMITTED BIO-DIESEL FUELS
Originally only rape seed oil methylester (RME) was sold as a
bio-diesel fuel in Europe but fatty acid methylester (FAME)
based on other oils have come onto the market increasingly in
recent years. However, with the latter there is a risk that the limit
values of EN 14214 are not kept in the field. Anyone who uses
bio-diesel fuel in DEUTZ engines must therefore choose his
supplier very carefully and have him guarantee compliance
with the EN 14214 limit values. Since experience has shown
that rape seed oil methylester (RME) exceeds the limit values
less often that other esters, it is expressly recommended to use
only rape seed oil methyester. DEUTZ customers in Germany
can additionally ensure the quality by buying bio-diesel fuel
with an AGQM certificate (Arbeitsgemeinschaft Qualitäts-Man-
agement Biodiesel e.V.).
The use of US bio-diesel based on soy oil methylester is only
permissible in mixtures with diesel fuel with a bio-diesel part of
a max. 20 weight-%. The US bio-diesel used for the mixture must
comply with the ASTM D6751-07a (B100) standard.
APPROVED ENGINES
The 912, 913, 914, 1011, 2011, 1012, 2012, 1013, 2013, 413 and
513 series are approved for bio-diesel from year of manufac-
ture 1993 under compliance with the basic conditions speci-
fied below.
BASIC CONDITIONS TO BE OBSERVED
• A power loss of 5-9 % in relation to diesel fuel in accor-
dance with EN 590 is possible due to the lower heating
value. Blocking of the fuel injector is not allowed.
• The lubricating oil quality must correspond to TR 0199-
99-3002. The lubricating oil change interval must be
halved in relation to operation with diesel fuel in accor-
dance with EN 590.
• Standstills of longer than 4 to 6 weeks must be avoided
with bio-diesel. Otherwise the engine must be started and
stopped with diesel fuel.
• Bio-diesels can be mixed with normal diesel fuel but the
basic conditions described in this subsection apply for mix-
tures. Mixtures with up to 5 % (m/m) bio-diesel (B5) which
have recently been on sale at European fuel stations are
excepted. These fuels must be treated like normal diesel
fuels because EN 590 expressly permits adding up to 5 %
(m/m) bio-diesel in accordance with EN 14214.
• Approx. 30-50 hours after changing over from diesel fuel to
bio-diesel, the fuel filter should be changed as a preventive
measure to avoid a drop in performance due to clogged fuel
filters. Deposited fuel ageing products are dissolved by bio-
diesel and transported into the fuel filter. They should not
be changed immediately but after approx. 30 to 50 hours
because the dissolving of dirt takes a certain amount of
time.
